SHEET HOT ROLLING METHOD Russian patent published in 1995 - IPC

Abstract RU 2040983 C1

FIELD: metal rolling. SUBSTANCE: method comprises steps of performing rolling operation of single billet at temperature α+γ of conversion with reduction values, equal to (25-40)% over a pass: performing pack rolling operation at temperature , equal to (0-50)C upon lowering the reduction value to the last pass by 1.6 times; guiding the single billets to rolls with displacement towards a side from a mean plane of the rolls; upon pack rolling of blanks tilting them at least one time and limiting a camber value of sheets by a value, equal to a product of a number of sheets of the pack by an allowance for a ready sheet thickness. That allows to eliminate welding of sheets in the pack. EFFECT: enhanced efficiency. 4 cl, 3 tbl
